Property and Performance Prediction of Meta Composites for Novel Applications

C. Thiagarajan[1]
[1]ATOA Scientific Technologies Private Limited, Whitefield, Bangalore 560066, India.

Metacomposites are new class of materials with unusual properties that can be engineered using existing materials with usual properties. The unusual properties of metacomposites are derived from the structure, analogues to atomic arrangement in crystal lattice. These material exhibits ... Read More

Designing Polymer Thick Film Intracranial Electrodes for use in Intra-Operative MRI Setting.

G. Bonmassar[1], and A. Golby[2]
[1]AA. Martinos Center, Massachusetts General Hospital, Charlestown, Massachusetts, USA
[2]Department of Neurosurgery, Brigham and Women’s Hospital, Boston, Massachusetts, USA

A new type of MRI compatible intracranial electrode based on Polymer Thick Film (PTF) is presented and studied using COMSOL Multiphysics. The geometry considered was a two-dimensional cross section cut of 5 mm thick electrodes with 5 cm leads on top of a 2×10 cm slab representing ... Read More

This poster presents the electric field flowing through an insulated cable due to a high frequency voltage pulse in the presence of water trees. Read More

An Efficient Finite Element Analysis on an RF Structure Used to Evaluate the Effect of Microwave Radiation on Uveal Melanoma Cells

A. Dulipovici[1], D. Roman[2], I. Stiharu[2], and V. Nerguizian[1]

[1]École de technologie supérieure, Montreal, Quebec, Canada
[2]Concordia University, Montreal, Quebec, Canada

The use of Microwave/RF energy on cancer cells is explored for tumor ablation using medium power level ranging between a few Watts to about 50 Watts. In this research, low power levels, less than 100 mWatt, are used to evaluate the effect of this energy on Uveal melanoma cells by ... Read More

Y. Koike [1], M. Hashiguchi [2], D. Mi [2],
[1] Department of Electronic Engineering, College of Engineering, Shibaura Institute of Technology, Koto, Tokyo, Japan
[2] Engineer Division 1, Keisoku Engineering System Co., Ltd., Chiyoda-ku, Tokyo, Japan

In the field of electronic, electro-acoustic apparatus is one of the important applications. There is an acoustic class in the department of electronic engineering, Shibaura Institute of Technology. The class is “Acoustic systems” which opens in 2nd semester of 3rd year. To foster the ... Read More

Implementation of an Active Fluid Cooling Design in a 48 V High-Power Battery Module

Z. Wu [1], A. Stawarski [2], H. Kemper [2],
[1] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany; RWTH Aachen University, Aachen, Germany
[2] Energy Storage Systems, FH Aachen - University of Applied Sciences, Aachen, Germany

Individual batteries have their own operational temperature ranges, which shall be respected to avoid both damaging of the cells and shortening of the cycle life. In terms of the Li-Ion cells, many of them do not function well at higher temperatures. Therefore, a better understanding of ... Read More

3D Modeling of Planar Discharge of a CO2 Laser

J. Schüttler [1],
[1] Rofin-Sinar Laser GmbH, Hamburg, Germany

High power CO2 lasers have been the workhorses for sheet metal cutting, welding and many more applications in materials processing during the past decades. Even though a significant replacement by fiber coupled lasers takes place, there are still many applications that benefit from the ... Read More

Electromagnetic Simulation of Split-Core Current Transformer for Medium Voltage Applications

N. Paudel [1], V. Siddharth [1], S. Shaw [1], D. Raschka [1],
[1] ABB, Inc., Instrument Transformers & Distribution Components, Pinetops, NC, USA

In electric distribution network, current and voltage measurement for metering, monitoring, and protection & control applications is done via instrument transformers (current and voltage transformers). These measurement devices are deployed during the construction phase of the ... Read More

Simulation of Horn Driver Response by Direct Combination of CD Frequency Response and Horn FEA

D. Cinanni [1],
[1] Ciare S.r.l., Italy

Today a horn driver developing is still time and cost consuming. In addition compression driver behavior depends by the horn profile. In this study is proposed a new technique to model a combination of an existing compression driver and a virtual horn, in order to predict the horn driver ... Read More

Sound Pressure Amplification Using FP Resonance of Acoustic Metamaterial Cavity

J. Kim [1]
[1] Department of Mechanical Engineering, Hongik University, South Korea

Metamaterials are periodic or quasi-periodic, sub-wavelength metal structures. The material properties are derived from its structure rather than inheriting them directly from its material composition. Read More
